Rocket Lab's latest test launch hasn't quite gone to plan after two rogue vessels were spotted in the vicinity.
The Electron rocket failed to make it into the skies on Saturday with the launch put on hold in the final moments, due to the vessels.
A second attempt later in the day didn't come to fruition either due to weather implications.
This was Rocket Lab's second attempt to complete the test launch - in December it came within two seconds of lift-off before the countdown was aborted because of "rising liquid oxygen temperatures" not compatible with the afternoon's warm conditions.
Shortly after, it suspended launch attempts until early 2018.
The flight will be the second for Rocket Lab and will carry small Earth-imaging satellites for US companies Planet Labs and Spire Global.
The company's inaugural test last May reached space but didn't make it into orbit after a communication fault forced the flight to be aborted early.
Rocket Lab will make another attempt to launch on Sunday afternoon.
